17 S y s t e m D e s c r i p t i o n 2 S Y S T E M D E S C R I P T I O N The functional elements of the system are pictured in Fig. 2. FIG. 2 FUNCTIONAL ELEMENTS OF CONNECT DUO DSP 2: MPEG Codec 2.1 Functionality The Connect Duo System incorporates an analogue POTS interface as well as an ISDN telephone interface. The operating modes can be configured by software. If the ISDN interface is used, depending on the operating mode two independent channels are available that can be used independently from each other. The complete signal processing is taken over by two digital signal processors. In this way the following functions are realised: DSP1: G.711 Audio encoding and decoding G.722 Audio encoding and decoding Signalising management (ARTIST, SFRM) Control of the complete system (Keypad, display, relays, TTL, RS232) Via the main Audio channels the high quality Audio signal is inserted or output analogue or digitally. If the digital AES/EBU Audio interface is used, two separate Sample Rate Converters are available for automatic clock synchronisation. For external clocking a clock input and a clock output are available PAGE 17

18 S y s t e m D e s c r i p t i o n DSP2: As an option a second DSP module can be equipped. In this case the ISO/MPEG 2 Layer II/III audio coding algorithm will also be available. ISO/MPEG 2 Layer III Encoder/Decoder Option: ISO/MPEG 2 Layer II Encoder/Decoder Compatibility: Orban MusicTaxi, Mayah Centauri, CCS, TELOS etc. The configuration and operation can be primarily carried out via the front keypad and the illuminated display. Configuration and control is especially comfortable with the Connect Duo Windows PC Software which is included in delivery and which communicates with the system via the RS232 interface. The basic operating functions like accepting a call, dropping a connection and establishing a connection with a preprogrammed number can be carried out via three programmable TTL contacts. Two relays are available for status indication. PAGE 18

19 P u t t i n g t h e s y s t e m i n t o o p e r a t i o n 3 PUTTING THE SYSTEM INTO OPERATION 3.1 Mounting With its dimensions (W H D) of 220 mm 44,5 mm (1 U) 220 mm the Connect Duo System can be used either as desktop device or mounted in 19 inch racks. Corresponding 19 mounting brackets are included in delivery. Optionally, a mounting kit to install two Connect Duo next to each other is available. When mounting the unit please keep in mind that the bending radius of the cables is always greater than the minimum allowed value. When the Connect Duo Audio Codec is installed, please make sure that there is sufficient ventilation: It is recommended to keep a spacing of ca. 3 cm from the openings. In general, the ambient temperature of the system should be within the range of +5 C and +45 C. These thresholds are especially to observe if the system is inserted in a rack. The system works without ventilation. TIP The system temperature can be indicated on the display (Menu Status information (see CHAPTER A1.4, Page 85)) During operation air humidity must range between 5% and 85%. ATTENTION! Incorrect ambient temperature and humidity can cause functional deficiencies Operation outside the threshold values indicated above leads to a loss of warranty claim. 3.2 Connection to the mains voltage The system can be operated with mains voltages in the range from 90 V to 253 V via the external power supply included in delivery. The line frequency can vary from 45 Hz to 65 Hz. The maximum power consumption is 15W. The rack must be earthed according to the VDE Regulations. The earthing can be carried out via the earthing screw on the back side of the unit. The unit does not have a circuit closer and a circuit breaker. After plugging in the external power supply the system boots within a few seconds. In standby mode the Connect Duo logo is shown on the display. PAGE 19

20 P u t t i n g t h e s y s t e m i n t o o p e r a t i o n 3.3 Earthing of the system For EMC reasons an earthing via the earthing screw of the system must be carried out in either case. ATTENTION! Earthing A lacking earthing can cause functional deficiencies within the unit. 3.4 Operational elements on the front side The system has an illuminated graphical display with a resolution of 160 x 32 Pixels and 21 operating buttons. On the right next to the display there are two softkeys whose current functions are indicated on the display. In the middle there are two buttons for navigation (selection upwards/downwards), two buttons for accepting/dropping calls as well as an button. The numerical pad supports in addition to the numerics the * and # key. For text entries the numerical pad can also be used as normal keypad. The operation is similar to standard mobile telephones.

21 P u t t i n g t h e s y s t e m i n t o o p e r a t i o n 3.5 Operating modes of the system The figures below show the systems in the different operating modes and their wirings. NOTICE In the wiring diagrams the AES/EBU interface is used for normal operation with the Control Panel or Digital Matrix. The AES/EBU interface allows direct panel dial-out and auto-routes incoming calls depending on who is calling in. The available analogue Audio interface can also be used, but remote control via the panel is in this case not possible Analogue POTS operation ATTENTION! Earthing If the analogue POTS interface is in operation the system must be earthed via earthing screw for EMC reasons. If the earthing is not carried out, the Audio signal can be faulty on the caller s side (humming). The minimum wiring for the operation with an analogue telephone line is pictured in Fig. 4.

PAGE 40

41 W i n d o w s P C S o f t w a r e Submenu CONNECT DUO Configuration Line Interface Via the submenu CONNECT DUO the system can be configured comfortably. It is distinguished between Basic Settings, which do not have to be changed during the operation and the actual Configuration for the current application. In contrast to a configuration, the basic settings cannot be saved as Preset (see CHAPTER 5.5.3). All settings made under Configuration can be saved as Preset. Via the option Line Interface the ISDN interface and the POTS telephone interface can be configured. FIG. 13 LINE INTERFACE General Via the option Line Mode you can select the line interface. The following configurations are possible: POTS: The system is connected to an analogue telephone line. In this operating mode only one channel is available in general. Only the Audio1/AES IN/OUT interfaces (see Fig. 6 and Fig. 7) are used. ISDN: The system is connected to the ISDN and two independent channels are available. ISDN leased line: The system is connected to an ISDN leased line. Two independent channels are available. ISDN leased line (B1 only): The system is connected to an ISDN leased line. Only the first B channel is used. ISDN leased line (B2 only): The system is connected to an ISDN leased line. Only the second B channel is used. PAGE 41

42 W i n d o w s P C S o f t w a r e Via the function Enable Auto Answer the auto answer can be activated. Using the Delay slider a period in a range from seconds can be configured after the system should answer a call. It is possible to activate a ring tone as audible signal for incoming calls via the function Enable System Ringing Tone. If the POTS 50 Hz Filter is activated, a disturbing 50 Hz humming is filtered out. The spurious signal is injected via the POTS connection in the system.the reason is in the majority of cases an incorrect cabling of the private branch extension. Prefix number NOTICE The following configurations are only necessary if the system is operated with a private branch exchange. Under Length of internal telephone numbers the length of your internal telephone numbers is set. Subsequently, the prefix number is automatically dialled first if the length of the telephone number exceeds the length specified in this setting. If you do not want to use this function or if you operate the system with a main telephone station, enter 0. Examples: Length of internal telephone numbers: 3 Entered telephone number: 130 Dialling: 130 Length of internal telephone numbers: 3 Entered telephone number: Dialling: Under External prefix number please enter the prefix number that you need to get an external line. In most cases it is 0. ATTENTION! You need to enter the prefix number at any rate if you work with a private branch exchange because otherwise the system does not wait for the free-line signal. Without dialling the prefix number at a private branch extension the telephone number is transmitted too fast and no connection can be established. Some private branch exchanges transmit telephone numbers with prefix number to the system. If you enable the function Skip prefix number on incoming call, you can save a displayed number in the phone book without prefix number since the prefix number of the displayed number is deleted automatically. PAGE 42

43 W i n d o w s P C S o f t w a r e MSN (Multiple Subscriber Number) NOTICE A MSN can only be set if the ISDN operating mode is selected (see Page 41 - General). Note, that only the last eight cyphers of a MSN can be entered. Normally, a MSN entry is not required. However, if you operate further units on your ISDN interface, you can allocate a certain number to a certain unit by a MSN entry. When you order an ISDN user port in Germany, you usually receive three MSN, which you can use for your connected units. Example: You operate a telephone, an ISDN PC card and a Connect Duo system using one ISDN interface. You received the following MSN from your provider: , , If no MSN is allocated to the system, all three devices respond to an incoming call no matter which of the three telephone numbers has been called. However, if a MSN is allocated to each device, the unit only responds if the corresponding number is called. For instance, if you enter the MSN for the Connect Duo, the system only signalises an incoming call if the subscriber has dialled the This example, however, requires that you enter the same MSN for MSN 1 and MSN 2. Please enter the desired MSN in MSN 1 respectively MSN 2. Of course, you can allocate the same MSN to both B channels. Please notice that a MSN is always entered without the area code. In the operating mode ISDN leased line no MSN can be entered NOTICE For some private branch exchanges the entry of a MSN is obligatory since otherwise no operation is possible. If you cannot establish a connection to a subscriber with the Connect Duo, however, you are sure the ISDN is working correctly, please enter a MSN on trial. Dial In Numbers (Access Protection) To avoid unauthorized incoming calls an access protection via the Dial in Numbers can be used. Only the listed numbers will have access to the system. ATTENTION This functionality requires the transmission of the Caller ID of the remote partner.! To add a new entry press the Add button. The Edit button allows an editing of an existing entry which must be selected in the list. An existing entry can be deleted by using the Delete button. PAGE 43

44 W i n d o w s P C S o f t w a r e Transmission Modes Via the Transmission Modes settings the Default Audio Mode can be defined. ATTENTION! This function is only in ISDN and ISDN leased line modes available. In POTS line mode only a G.711 Telephone Audio transmission is possible. FIG. 14 TRANSMISSION MODES For both channels the Default Audio Mode can be configured separately and will be set automatically after disconnecting a line. The following settings are possible: OFF G.711/Telephone G.722/SFRM G.722/Artist PAGE 44

45 W i n d o w s P C S o f t w a r e Signal Processing ATTENTION! The Signal Processing feature is only for G.711/Telephone connections relevant. With the option Signal Processing configurations to optimise the caller signals can be carried out. It is possible to configure the AGC (Automatic Gain Control), the Echo Canceller as well as the Expander. FIG. 15 SIGNAL PROCESSING Line Settings A separate Automatic Gain Control (AGC) can be switched on for both channels. ATTENTION! An Automatic Gain Control is reasonable if you do not have the possibility to adjust the level manually. But: An AGC is no wizard. Extremely low callers cannot be boosted boundlessly. Extremely loud callers cannot be toned down boundlessly. Please select the desired line with your mouse and press the button Edit, which opens the configuration window. To switch off the AGC select Off. To switch it on select On. FIG. 16 CONFIGURATION AGC AND ECHO CANCELLER PAGE 45

46 W i n d o w s P C S o f t w a r e Via the button Set AGC on/off for all lines you can switch on respectively switch off the AGC for all lines. An Echo Canceller can be set on or set off separately for each channel. NOTICE In general, the use of the Echo Canceller is recommended. When a subscriber calls on the system with an analogue telephone, a line echo is produced which can interfere with the incoming signal. Digital telephones (e.g. ISDN or mobile phones) do not produce these line echoes. In this case an Echo Canceller would worsen the incoming signal. For this reason the system sends a short test tone when a connection is established (only in the Auto mode) and detects the level of the echo. If a certain threshold value is not exceeded, the Echo Canceller is set off because the use of a digital phone on the counterpart is anticipated. If the level is too high, the Echo Canceller is set on automatically. But: Echo Cancellers can only suppress echoes if the delay of the signal lies within a certain scope. Telephone connections via satellite have such a long delay that the Echo Canceller cannot work properly anymore. Select the desired line with your mouse and press the button Edit, which opens the configuration window (see Fig. 16). To generally set the Echo Canceller off select Off. If you always want to have the Echo Canceller activated select Always ON. In this case, no test tone to detect the echo is sent. If the option Auto is selected, the Echo Canceller is switched on or switched off dynamically. The system sends a short test tone to determine if an Echo Cancelling is required or not. Via the button Set EC on/off/auto for all lines you can select the same operating mode of the Echo Canceller for all lines. Automatic Gain Control Settings (AGC)/Expander The correct functioning of the AGC can be optimised via several parameters. Threshold : The AGC does not start before the signal exceeds the threshold value set here. The default setting is -30 dbu. Level :The level set here corresponds with the average desired level. Please consider sufficient head room. The default setting is -12 dbu. Speed : Depending on the desired speed of the level adjustment (Slow or Fast) the setting of the AGC speed can be configured here. The faster the AGC must work the more noticeable are the inconsistencies. If the set speed is too slow, the caller signal is too low or too loud on average. The default setting is Medium. An Expander tones down the caller signal automatically, if its level falls below a certain threshold value. The aim is to completely filter out background noises of callers who are not currently speaking.the Expander is activated by checking the respective box. With the use of the key Default Settings the default settings named above can be configured and the Expander can be activated PAGE 46

Display The Display has a backlight. Under the setting Backlight you can switch it ON permanently. If you select the option Auto the backlight is turned off automatically 60 seconds after the last keystroke. The backlight is activated again by pressing any key (e.g. Ok). NOTICE Please notice that if the keypad lock is activated, the backlight is only switched on again by pressing the key sequence Menu *. Via the slide control Contrast you can adjust the contrast in the range for the display. The default setting is 0. RS232 Interface If you want to operate the system with the PC, you must set the data rate in accordance with the interface. There are five baud rates available: PC (9600 Baud), PC (19200 Baud), PC (38400 Baud), PC (57600 Baud) and PC ( Baud). PAGE 47

48 W i n d o w s P C S o f t w a r e Audio Interface Connect Duo supports analogue as well as digital AES/EBU Audio interfaces. If the digital interfaces are used, a separate Sample Rate Converter is available for the input and the output so that external adjustments are not required if there are different digital sources and drains. NOTICE The digital AES/EBU Audio interface should be used as standard Audio interface. Otherwise a remote control from a Control Panel or a Digital Matrix is not possible. FIG. 18 AUDIO INTERFACE Audio Interface The operating mode analogue or digital can be set separately for the Audio Input and the Audio Output. If the output is set digital, additionally the configuration for the AES/EBU Interface is displayed. Under Clock Source of digital output you can select the following options: Internal: The AES/EBU output clock is derived from the internal system clock. External: The AES/EBU output clock is derived by the external clock connected via the interface Audio 2/CLK IN. The clock rate of the connected clock must be 48-kHz. Recovered: The AES/EBU output clock is derived from the digital input signal of the interface Audio 1/AES IN. This configuration is usually to be selected if you use the digital input of the system. In this way a synchronous functioning of the transmission chain is ensured NOTICE The AES/EBU input always works with recovered clock, therefore a configuration of the output is required. For clock synchronisation to other systems you can use the Audio output Audio 2/CLK OUT. The clock rate of the output clock is 48-kHz. PAGE 48

49 W i n d o w s P C S o f t w a r e If you operate the input or the output in an analogue mode, the corresponding slide control for adjusting the nominal Audio level of the Audio interface (Main Nominal Level) is displayed. The nominal level can be adjusted separately for the input (Level In) and for the output (Level Out) in the range of dbu in 1-dB steps. The head room is 6 db in general. If you want to have the maximum level of 15 dbu for the system, you must set 9 dbu as nominal level. The default settings are 0 dbu. PAGE 49

50 W i n d o w s P C S o f t w a r e Relay / TTL The Connect Duo system incorporates three GPIO Pins (TTL) which can be programmed separately as input or output. Additionally, two Relays are available. The operating mode of a TTL-Pin - Input or Output is selected via the option Direction. The following specification accounts for all three configuration windows TTL1, TTL2 and TTL3. TTL-Pin as input FIG. 19 TTL-PIN AS INPUT If you use a TTL-Pin as Input, you can program two different functions separately when edges change: Positive edge: The event is activated when the voltage on the TTL-Pin changes from 0V to +5V.

FIG. 38 SUBMENU SYSTEM MONITOR Error Counter Under System alarms all potential alarms are displayed. A red LED signalises a currently existing alarm. How often the error occurred since switching on is displayed by the corresponding error counter. NOTICE If an alarm occurs frequently or over a longer period disconnect the unit from electricity. If the error occurs again after switching on, there is probably a hardware defect. The following errors are signalised: LCA: The communication with a programmable component is faulty. TIME KEEPER: The communication with the integrated clock module is faulty. A/D D/A CONVERTER 1: The communication with the first ADDA converter is faulty. A/D D/A CONVERTER 2: The communication with the second ADDA converter is faulty. TEMPERATURE SENSOR: The communication with the temperature sensor is faulty. FLASH EPROM: The communication with the permanent memory is faulty. Configurations cannot be saved or read anymore. PAGE 71

72 W i n d o w s P C S o f t w a r e MAIN EEPROM: The communication with the permanent memory is faulty. Configurations cannot be saved or read anymore. OVERHEATED: The system sets this alarm if the system temperature is higher than 57 C. Disconnect the unit from electricity or cool down the ambient temperature. TIP A system alarm can also be configured as relay output (see Page 50). The actual system temperature is displayed in C under System Temperature. The regular system temperature ranges from C. Under DSP Load the load of the system is displayed. The usual load is about 55 to 65%. Under System Logfile you can create a detailed ISDN log file. ISDN Layer 1: Physical Layer: All messages concerning the physical activation/deactivation of the ISDN interface are stored in this layer. ISDN Layer 2: Data Link Layer: The main task of the data link layer is to take a raw transmission facility and transform it into a line that appears free of transmission errors in the network layer. This layer should only be activated for the log file if there are potential problems. Please notice that if this layer is enabled an entry is generated every 8 seconds and therefore the memory is filled quickly. ISDN Layer 3: Network Layer: The Network Layer enables that a connection between two subscribers is established by adequate addressing. This layer is the most important one for the logging since all connection data is recorded here. The system saves all messages of the activated ISDN Layer. The internal memory capacity is 128-kByte 1. The data is filed cyclically. NOTICE Data can be analysed via the option ISDN S0 Monitor (see CHAPTER 6.2, Page 78). Our Support can also read these data via remote access. If you experience problems with your ISDN connection, please activate the desired ISDN layer of the system log file so that we can analyse it. ATTENTION When the unit is switched off, the saved data of the system log file is lost.! 1 An entry in the ISDN protocol is about 15 Byte on average. PAGE 72

73 W i n d o w s P C S o f t w a r e Submenu S0 Monitor (Option) NOTICE The function S0 Monitor is only available, if the fee-based option Remote Control & ISDN Monitor Plug-In is enabled and the necessary USB Dongle is connected to your PC.
